Multiphase PWM Regulator for VR12™ Desktop CPUs

ISL6363

Features

Fully compliant with VR12™ specifications, the ISL6363

provides a complete solution for microprocessor core and

graphics power supplies. It provides two Voltage Regulators

(VRs) with three integrated gate drivers. The first output (VR1)

can be configured as a 4, 3, 2 or 1-phase VR while the second

output (VR2) is a 1-phase VR. The two VRs share a serial control

bus to communicate with the CPU and achieve lower cost and

smaller board area compared with a two-chip approach.

• Serial Data Bus (SVID)

• Dual Outputs:

- Configurable 4, 3, 2 or 1-phase for the 1st Output with 2

Integrated Gate Drivers

- 1-phase for the 2nd Output with Integrated Gate Driver

• Precision Core Voltage Regulation

- 0.5% System Accuracy Over-Temperature

- Enhanced Load Line Accuracy

Based on Intersil’s Robust Ripple Regulator R3 Technology™,

the PWM modulator, compared to traditional modulators, has

faster transient settling time, variable switching frequency

during load transients and has improved light load efficiency

with its ability to automatically change switching frequency.

• PS2 Compensation and High Frequency Load Transient

Compensation

• Differential Remote Voltage Sensing

• Lossless Inductor DCR Current Sensing

The ISL6363 has several other key features. Both outputs

support DCR current sensing with a single NTC thermistor for

DCR temperature compensation or accurate resistor current

sensing. Both outputs come with remote voltage sensing,

ISL6363 also has an additional compensation function for

PS1/2 mode and high frequency load transient compensation.
